The way to careIn today’s medical world, comfort and safety are key requirements. Hospital environments become more and more complex and expen-sive, therefore effectiveness, reliability and speed are crucial.

Doctors need to be precise in their diagnostics and also fast. They have to rely on their equipment during examination, surgery and treatment procedures.

Workflow and speed are equally significant for patient safety and er-gonomic support. A focus on quality and reliability, coupled with supporting and monitoring services, can put a healthcare device manufacturer at the forefront of its industry.

Thanks to its deep knowledge of the medical industry, SKF has developed a unique range of products and services. Our advanced actuation and guiding systems, bearings and seals are manufac-tured to meet the industry’s requirements and to comply with all specifications and regulations of the medical industry, such as those required by EN and UL standards.

From concept to product launch, SKF strives to achieve maximum quality and safety.

SKF offers a full line of products especially designed for medical ap-plications which provides:

High performance and reliability•Compact and robust designs•Compliance with standards and regulations•Extensive industry experience and knowledge•Global presence and knowledge support•

Business is not just about selling products; it is about providing so-lutions. SKF’s goal is to build an innovative, creative and meaning-ful partnership with customers to improve their competitiveness and create added value. SKF’s engineers provide solutions that op-timize the performance of the equipment while helping medical design engineers achieve their goals of reliability, enhanced per-formance, and safety.

Bucky systemsSKF actuators, pillars and profile rail guides are specially designed for versatile and efficient radiographic procedures in order to increase pa-tient comfort with reduced positioning time and efforts. They require minimum space for easy integration into the equipment and are con-veniently controlled and adjusted. Thanks to SKF state-of-the-art products, table designs can be more open and more easily accessible, al-lowing better access for the patient.

Mobile C-armBy listening to our customers, employing cutting-edge motion technologies, and keeping constant vigilance on quality, SKF sets the trend for continuous technological advancement in surgical imaging. SKF Actuation System pillars and SKF profile rail guides help to reduce installa-tion and maintenance costs and are designed to take large offset loads. In addition, the vertical movement solution provided by the pillars represents an attractive alternative to self-made guiding solutions. To identify your own solution and obtain the optimum in lift functions, see SKF’s extensive actuator and linear guidance range.

Surgery table/Ceiling systemSurgery tables requires products capable of handling high loads and very low retracted height for easier patient access. SKF offers a unique range of pillars and actuators for height adjustment, Trendelenburg and backrest movement. For a more complete solution, SKF also pro-vides compact and single fault safe control units as well as operating switches. For ceiling applications, SKF recommends several combina-tions out of its large tubeset series, from 2 to 7 sections. All tube sets are nearly play free adjusted and virtually maintenance-free. Their modular designs allow flexibility and quick time to market. In combination with SKF’s linear guiding, SKF is the partner to assist you in every variation of your application.

CT ScannerPrecise movement, stiffness, and reliability are some of the key factors when it comes to CT patient tables. Over years of partnership with customers, SKF has developed tailored solutions and gained a high level of expertise in the medical imaging field. Thanks to the precision of SKF pillars and profile rail guides, the image quality is improved and patients’ stress is reduced to its minimum. Telescopic solutions provide easy and safe patient entry with maximum lift functionality.

IncubatorModern designs of incubators reduce the stress for babies and minimize the numbers of transfers from incubators to beds. Therefore, incu-bators require drive solutions with very smooth movement. Incubators require pillars with very smooth movement to help keep babies safe and comfortable. Thanks to its long experience with medical equipment, SKF has identified such needs and developed pillars to fulfil the exact needs and requirements of baby care, such as soft- start and stop, extreme quiet operation and virtually vibration free movements.

Ophthalmic equipmentSKF provides reliable and attractive solutions for ophthalmic chairs, tables and furnitures. The various compact and modern pillar designs, combined with high lifting loads, offer quiet and safe operations of patients and devices. Furthermore, the pillar range includes special add-ons, such as AC inlets and outlets, integrated control units or nice looking handsets, to fit perfectly into design requirements. SKF’s high pre-cision ground rail systems offer a unique smooth and soft movement in ophthalmic furniture with maximum stiffness.

Dental equipmentTo help adjust the height of dental chairs, and thus facilitate patient access, SKF offers a distinctive telescopic pillar, the Telemag TLT. Together with linear actuators and control units, SKF can provide the right motion solution for Trendelenburg and backrest functions. In addition, new features like “home” buttons and “walk away” functions help doctors reduce time between surgeries. For dental X-Ray wallstands, SKF’s know-how makes it easy to use drive units which can be integrated into a customer’s profile or implemented as a complete function.

IVD instrumentsThe dominant requirement in IVD instruments is to improve efficiency and consequently cut cost. Therefore, SKF offers guidance compo-nents for high speed and high precision positioning to achieve a better throughput in syringe dispensing of tiny volumes of fluids, automatic dispensing and sampling of chemicals, DNA processing or similar applications. As those different applications require specific solutions, a wide range of guidance components is available to meet those demands: miniature slides for short strokes, space-saving miniature profile rail guides for unlimited strokes, profile rail guides to accommodate high loads and precision rail guides when highest accuracy is required. Even more, SKF can support you by developing complete Mechatronic units, including motorization and linear measurement.
